Earnings for the period July 10, 2009 through December 31, 2009 and the years ended December 31, 2008, 2007 and 2005 were inadequate to cover fixed charges. Additional earnings of $5.0 billion, $23.0 billion, $4.4 billion and $16.6 billion for the periods July 10, 2009 through December 31, 2009 and the years ended December 31, 2008, 2007 and 2005 would have been necessary to bring the respective ratios to 1.0.

In January 2009 Old GM adopted ASC 810-10, “Consolidation,” that governs the accounting for and reporting of noncontrolling interests in partially-owned consolidated subsidiaries and the loss of control of subsidiaries. In addition Old GM adopted ASC 470-20, “Debt with Conversion and Other Options” which requires issuers of convertible debt securities within its scope to separate these securities into a debt component and an equity component, resulting in the debt component being recorded at fair value without consideration given to the conversion feature. Accordingly, the presentation and disclosure requirements have been applied retrospectively and prior period amounts for all periods presented have been adjusted to apply the new methods of accounting.
